High-quality monoenergetic proton generation by sequential radiation pressure and bubble acceleration
Two-dimensional particle-in cell simulation shows that protons in a small target located in an underdense high-mass plasma can be accelerated by the radiation pressure of a short circularly polarized laser pulse as well as by the wake bubble field of the laser in the background plasma. The radiation...

| description | Two-dimensional particle-in cell simulation shows that protons in a small target located in an underdense high-mass plasma can be accelerated by the radiation pressure of a short circularly polarized laser pulse as well as by the wake bubble field of the laser in the background plasma. The radiation-pressure preaccelerated protons are easily trapped and accelerated stably in front of the bubble for a relatively long distance. It is found that a quasimonoenergetic proton beam of 38 GeV peak energy and 12.6% energy spread as well as small divergence angle can be obtained with a 10^{23} W/cm^{2} 18.26 kJ laser pulse in a tritium plasma of density 5.2×10^{20} cm^{-3}. |
